[A case of hepatitis B virus reactivation in a patient with prior resolved hepatitis B infection during bevacizumab plus FOLFIRI treatment].

Hepatitis Bvirus (HBV)reactivation induced by cancer chemotherapy is increasingly being observed. However, most reports of resolved HBV[hepatitis Bsurface antigen(HBs-Ag)negative and hepatitis Bsurface antibody(HBs-Ab)positive and/or hepatitis Bcore antibody(HBc-Ab)positive]infection involve patients with hematological malignancies, whereas few describe patients with solid cancers. In this study, we report our experience with a patient with resolved HBV infection who was undergoing bevacizumab plus FOLFIRI treatment for rectal cancer when HBV reactivation was noted.
